Andrew Lloyd Webber's Diamond Jubilee royal tribute top charts

Andrew Lloyd Webber has another hit single -- this time fit for a queen.

"Sing," the official song of the Diamond Jubilee, is the top-selling song of the year and the album of the same name also reached No. 1, ousting Adele's Grammy-winning album "21" from top 10 for the first time in 18 months.

The last time Lloyd Webber performed such a musical feat was in 1976 when the album for Evita and "Don’t Cry for me Argentina" were simultaneously at the top of the charts.

The single, which sold more than 142,000 copies since last week, was presented to Queen Elizabeth II on June 4 to mark her 60 years on the throne. Lloyd Webber plays piano, Prince Harry plays the tambourine and vocals are from the Military Wives Choir.

The often mum Queen has formally given “Sing” her seal of approval. "And we're very pleased about that, because she doesn't normally comment," Lloyd Webber told the Daily Mail.

The legendary composor said that while the sentimental song was written to commemorate what the Queen has done for the Commonwealth, he wanted the tune to carry beyond the occasion.

"We wanted it to stand the test of time in its own right," he said. "A lot of people found it a very emotional song. It has real heart, and it appeals to people across the generations."

Lloyd Webber penned the tune with Gary Barlow, the frontman of poppy British band Take That and a judge on the U.K.version of "The X Factor.” While Lloyd Webber has hinted that he could join Barlow at the judge’s table, the composer currently has a reality show in the works casting the title role of "Jesus Christ Superstar" in the U.K.
